Marine grade isn’t a vibe. It’s a standard.
Not all decking that looks coastal is actually built for coastal conditions.
Lumberock Coastal is engineered with a solid HDPE core and no wood fibers or organic fillers, so it delivers the kind of performance waterfront projects demand. That means zero water absorption, no rot, no swelling, and long-term durability in marine and high-moisture environments.
While others may claim to be marine grade, what matters most is what’s inside.
Why Lumberock Coastal?
100% waterproof core
No organic fillers
No wood fibers
Built for docks, marinas, and coastal homes
Designed for long-term durability near the water
When you’re building near the water, choose a board that was made for it.
Lumberock Coastal — Built for the water. Built to last.
